' CUT-OUT MECHANISM FOR ELECTRICALLY-OPERATED MACHINES.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed. December 27, 1906. Serial No. 349,630.

To all whom it may concern: I

Be it known. that we, GEORGE S. Concert,

and CnARLns PEARCE, citizens of the United States, and residents, respectively, of the borough of Brooklyn, in the city and State v of New York, and of the borough of Mantrically operated machines with the object in view of providing a simple and effective cutout for stopping the waste of eleotrlo current when the machine is for any reason tem porarily out of use.

We have chosen to illustrate our invention, a practical embodiment of it as a plied to a printing telegraph machine, alt rough the invention is not limited in its use to that particular machine.

,In the accompanying drawings, Figure 1 is a partial top plan view of a machine embodyin'g' our invention, and Fig. 2 is a vertical transverse section in the plane of the line i The parts of the conductor-by the electrichcurrent issupplied to operate the machine and which are interrupted by se arable contact pieces are denoted byl an. 2 the part 1 being electrically connected with the contact piece 3 at 4 and the part 2 with the contact piece 5 at 6. The pieces 3 and 5 arcsu ported by an insulating block 7 located etween them and the piece 5 which is a sprinipiece has a normal contact with the piece 3 y means of a post 8 fixed to the piece 5 and resting against the piece 3.

The circuit will be broken and themachine stopped whenever the piece 5 is sprung away from the piece 3, and such movement of the piece 5 to break the circuit is effected by a pin 9 set in the face of a spur wheel 10 mounted in suitable bearings in a swinging arm 11 pivoted at 12.

The spur wheel 10, by the swinging of the arm 11, may be placed into and removed from the pinion 13, which is carried by a shaft 1 1, which is continuously rota ting during the operation of the machine, in the pres ent instance, by the current through the con- "tact pieces 3 and 5. A rock shaft 1.5 carries an arm 16, the free end of which engages the under side of the arm 11 which carries the spur Wheel 10. The shaft 15 is rocked in the direction to lift the arm 15 and hence the arm 11 and spur wheel 10, by the armature 17 of an electro-magnet 18, the said armature being attached to a bar 1'9 fixed on the shaft 15. The shaft 15 and hence the arm 16 is rocked in the opposite direction, to lower the arm 11 and hence the spur wheel 10, by means of a sprin 20 connected at one end to an arm 21 fixed to the shaft 15 and at its opposite end to a screw 22 set in a post 23 on the main frame for adjusting the tension of the spring,

The arm 11 is drawn downward or in a direction to hold the spur wheel 10 in engagement with the pinion 13, by a spring 24. The spur wheel 10 is under spring tension bymeans of a spring 25, tending to rotate it in a direction opposed to that in which it is driven by the pinion 13.

In operation, so long as the elcctrdmagnet 18 is benw energized, either continuously or at frequent intervals as is common in printing news, the wheel 10 will not advance, or will. make short advances only which willbe offset, by the. retrograde movements of the wheel under the action of its spring 25 whenever the wheel 10 is momentarily .re leased from the pinion 13, but, when the electromagnet 18 is allowed to rest for any considerable length of time, as during' )auses between news items, the wheel 10 wi continue its PI'OGIGSSIVQ movement unt l the pin 9 engages die free'end of the contact piece 5 and draws it out of contact with the piece 3/ machine actuating current during 'short intervals in the use of the machine and for stopping the said current during long ine tervals con'ip'rising a-movable contact piece for-making and breaking circuit, a rotary wheel movable through space for operating machine actuating current (luring short inl the contact piece, means for rotating the said ping the said current during long intervals wheel and means for moving the said wheel comprising a movable contact piece for mek-- through space. ing and breaking circuit, spring actuated 2.
